Features

2.4.29 Boot Assist Module (BAM)

The BAM is a block of read-only memory that is programmed once by Freescale. The BAM program is

executed every time the MCU is powered-on or reset in normal mode. The BAM supports different modes

of booting. They are:

•

Booting from internal flash memory

Serial boot loading (A program is downloaded into RAM via CAN or UART and then executed)

Booting from external memory

Additionally, the BAM:

•

Enables and manages the transition of the MCU from reset to user code execution

Configures device for serial bootload

Enables multiple bootcode starting locations out of reset through implementation of search for

valid Reset Configuration Halfword

•

Enables or disables software watchdog timer out of reset through BAM read of the Reset

Configuration Halfword option bit

2.4.30 IEEE 1149.1 JTAG Controller (JTAGC)

JTAGC features the following:

•

Backward compatible to standard JTAG IEEE 1149.1-2001 test access port (TAP) interface

Support for boundary scan testing

2.4.31 Nexus Development Interface (NDI)

Nexus features the following:

•

Per IEEE-ISTO 5001-2003

Nexus 2 Plus features supported

— Static debug

— Watchpoint messaging

— Ownership trace messaging

— Program trace messaging

— Real time read/write of any internally memory mapped resources through JTAG pins

— Overrun control, which selects whether to stall before Nexus overruns or keep executing and

allow overwrite of information

— Watchpoint triggering, watchpoint triggers program tracing

•

Configured via the IEEE 1149.1 (JTAG) port

Nexus Auxiliary port supported on the 176 LQFP package FOR DEVELOPMENT ONLY

— Narrow Auxiliary Nexus port supporting support trace, with 2 MDO pins

— Wide Auxiliary Nexus port supporting higher bandwidth trace, with 4 MDO pins
